Patented Feb. 1a 1930 mrans'rarEsPATENr QFFECE FRED K. nnnmarcxson, or wo MACHINE worms, or wmrrn onusnr'rs Application filed May 17,

This invention relates to means for supporting a series of yarn separators in a spinning or twisting frame. Such separators are commonly mountedin several sections, the

5 number of which varies with the length of the machine and may correspond to the number of ring rail sections.

It is the general object of my invention to provide improved mechanism by which a sepl arator section may be adjustably secured to a ring rail or other supporting structure.

Another object is to provide means by which the limits of angular movement of the separators to operative or inoperative posi- 15 tions may be readily changed or adjustec.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particuslotted arms 54 ofstands 55 larly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings in which v Fig. l is a front elevation of parts of a spinning frame embodying my improvements;

Fig. 3 is an enlarged end elevation of certain parts shown in Fig. 2;

Figs. 7 and 8 are front and side elevations of a cone connector; and

Figs. 9 and 10 are front and side elevations of a separator bar support.

Referring to the drawings, I have shown portions of a spinning frame including a spindle rail on which a series of spindles 21 are mounted for rotation of bobbins B supported thereon. The yarn Y is led downward through guide wires 22 in a thread board 24 and passes under a traveler 26 to the bobbin B. The travelers 26'are mounted on the usual p 29. Separator blades 80 are mounted on bars 31' extending lengthwise of the machine, the

bars being preferably made in sections'corresponding to the lengths of the ring rail secspinning rings 28 supported on a ring rail BCESTER, MASSACHUSETTS, ASSIGNOR TO WHITIN F5VILLE, MASSACHUSETTS, A CORPORATION OF lrIASSA- SEPARATOR SUPPORT FOR SPINNTNG FRAMES 1929. Serial No. 363,918.

The parts thus far described are in general of the usual construction and in themselves form no part of my present invention, which relates more particularly to the supports for theseparator bars 31.

Supporting members 40 are secured in spaced relation to the separator bars 31 in any convenient manner, as by clamping screws 42. The bars 31 are preferably noncircular in section and are seated in correspondinglyshaped recessesin the laterally 1 extending upper end portions 40 of the members 40. Thedepending arms of the members 40 are pivoted on bushings 42 supported by bolts 44 and secured thereon by clamping nuts 45.

The bolts 44 are m ounted in brackets secured by bolts 52 to depending (Fig. 2), which e secured to the under side of ail sections 29 by clamping stands may b the ring r screws 56. g

The outer face of each bracket 50 is provided with a cone shaped recess 60 (Fig. 5) in which a conical projection 62 on a cone con-c nector 64 is fitted. The connector 64 has a flange or project-ion 66 extending nearly half .way around its periphery and thesupportingmember 40 has a flange or projection 70 -(Figs. 9 and 10)i extending around substantially less than half of its circumference.

The parts are assembled as indicated in -Figs. 1 to 4, the stands being secured to the ring rail sections 29, and the brackets '50 beingvertically adjusted and secured to the depending slotted arms 54 of the stands 55. The bolts 44 extend through the brackets 50, the cone connectors 64, and the bushings 42 which rotatably support the members 40.

The flange or lug 70 on the supporting member 40 engages the flange or lug 66 on the cone connector 64 and angular movement of the supporting member 40 is definitely limited by such engagement. 7 Inthe use of the invention, the parts are assembled as above described and the cone connectors 64- are adjusted angularly until 'the's'eparatorblades throughout the length of the machine are aligned when in forward or tightened on the bolts 44, forcing the bushings 42 against the connector 64 and firmly seating the connectors in the brackets 50. The conical bearing surfaces of the bracket and connector firmly engage each other and correct alignment of the separators is thus readily accomplished and, reliably maintained. c

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is i 1. In a spinning or twisting frame having separator blades mounted in series on sectional separator bars, in combination, a supporting member for a sectional bar, a bracket mounted in fixed position, a bolt in said bracket on which said supporting member is pivotally supported, and a connector between said bracket and said supporting member, said connector and member having co-operating devices limiting angular movement of said supporting member relative to said connector.

2. The combination in a spinning or twistframe as set forth in claim 1, in which the bracket and connector have a co-operating conical projection and depression, and in which said connector is angularly adjustable on said bracket but is held clamped in adjusted position thereon by said bolt.

3. In a spinning or twisting frame having separator blades mounted in series on sectional separator bars, in combination, a supporting member for a sectional bar, a bracket mounted in fixed position, a bushing on which said supporting member is mounted for free angular movement, an angularly adjustable connector between said bushing and bracket, and a bolt to secure said bushing, said connector and said bracket together in adjusted relation, said connector and said supporting member having co-operating devices limiting angular movement of said member relative tosaid connector.

4. In a spinning or twisting frame having separator blades mounted in series on sectional separator bars, in combination, a stand mounted in fixed position in said frame, a bracket vertically adjustable on said stand, means to secure said bracket in adjusted position, said bracket having a conical recess in one side face thereof, a cone connector having a conical projection on one side face fitting said recess and having a segmental, flange on its opposite side face, a supporting member mounted adjacentsaid conical. connector and having a segmental flange co-operating with the flange on said connector to limit angular movement of said supporting member, a bushing on which said member is mounted for free an-gularvmovement, means to secure a sectional separator bar on said supporting member, and. means. to secure said bushing and cone connector on said bracket, said cone connector being angularly adjustable relative to said bracket to determine the angular position of said supporting member and separator blades. y In testimony whereof I have hereunto affixedmy signature.
